National Security Team and President Meet on Syria

President Barack Obama with top U.S. military and national security advisors have detailed a set of options for responding to the Syrian government’s alleged use of chemical weapons.

The White House  said the meeting was called to set an action plan — if it is determined Syrian forces used chemical weapons against civilians, as aid workers and rebels allege.

The White House also said the president conferred Saturday with British Prime Minister David Cameron, as the U.S. intelligence community continues to gather facts on the alleged chemical  warfare. Both men voiced “grave concern” about the weapons allegations.

The White House security meeting, attended by Vice President Joe Biden, CIA Director John Brennan and National Security Advisor Susan Rice — comes just days after accusations that more than 1,000 people were killed near Damascus in a chemical weapons attack.

The international medical relief group Doctors Without Borders, known by its French acronym MSF, said Saturday three Damascus hospitals have received about 3,600 patients displaying symptoms of exposure to neurotoxic agents.
